F. M. STEVENS. Rotary-Valve Patented July 16, 1878.
INVENTCIR.
To all whom it may concern:
Be it known that I, FRANK M. STEVENS, of Concord, in the county of Merrimack and State of New Hampshire, have invented certain Improvements in Valves for Engines, of which the following is a specification:
This invention relates to valves which rotate or oscillate in operative connection with fixed seats; and consists in various features of construction, which will be more particularly set -t-h hereinafter.
v In the drawings, Figure 1 is a vertical midon through the valve, its seat, and its er. Fig. 2 is a plan of the valve with amber in section. Fig. 3 is a side eleva fhe valve alone.

IMPROVEMENT IN ROTARY VALVES.
Specification forming part of Letters Patent No. 205,982, dated July 16, 1878; application filed October 9, 1877.
the top may be left open or cut away, and the bottom is chamfered at b, so that the steam may have access to the under edge of the valve, and thus counterbalance the pressure from above.
The axis of rotation of the valve may be arranged vertically, horizontally, or at any angle, and the valve may be used for any purpose where the passage of elastic vapors or gases in or out is to be regulated.
I am aware that oscillating valves are in common use, and that the arrangement of ports in a valve-seat and a valve so that they will coincide in certain positions of the parts is not new; but
\Vhat I claim as new is 1. The valve E, having a slightly-conical inner face, ground to fit a conical valve-seat, chamfered at I), made open at the top to admit the steam, and provided with a stem, F, and a slit or slits, a, all substantially as and for the purposes set forth.
2. The valve E, having a slightly-conical inner face, ground to fit a conical valve-seat, made open at the top to admit the steam, and provided with slits a a and a stem, I, and the whole inclosed within a chamber, C, having an outlet, G, and a space within the said chamber surrounding the valve E and communicating with the said outlet, all substantially as set forth.
3. A valve having a slightly-conical inner surface to fit a conical seat, an axial stem by which to rotate or oscillate it, and a chamfered bottom, as and for the purposes set forth.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
FRANK M. STEVENS.
